ASSIGNORS TO PLACE.-

THE LOEVVER SOLE-ROUNDER COMPANY, OF SAME SPECIFICATION forming part ofLetters Patent No. 558,004, dated April 7, 1896. Application filedDecember 5, 1895. Serial No. 571,169. (No model.)

T 00% whom it may concern.-

Be it known that we, LIBANUS M. TODD and JOHN J. LEARY, citizens of theUnited States, residing at Rochester, in the county of Monroe and Stateof New York, have invented a new and useful Improvement in Sole-RoundingMachines, of which the following is a specification.

This invention relates to an improved stockgage for use uponsole-rounding machines of the class which work upon block-stock, andmore especially upon machines of this class known as rotaryknifemachines in which the block-stock is turned in accordance with a patternand shaped by the action of the rotary knives.

The improvement as illustrated in the accompanying drawings is designedmore especially for use upon the Loewer sole-rounding machine, PatentNo. 502,421, dated August 1, 1893. In this machine the pattern andblockstock to be out are held between clamps to revolve on a swingingframe and upon the same axis. Adjacent thereto is a rotary shaftcarrying cutter-knives and a guide-roller, the operation being performedby the rotation of the pattern upon the guide-roller, wherebytheswinging frame is moved to change the position of the stock withrelation to the cutter-knives.

Block-stock, for the sake economy, is usually cut to asize but littlelarger than the sole which it is intended to form therefrom, and forthis reason it is necessary that the stock shall be positioned in themachine with great exactness. Hitherto it has been usual to employ astock-gage which was adjustable according to the pattern after thelatter had been placed in the machine, and while such stock-gages havebeen more or less satisfactory in operation so far as the positioning ofthe stock was concerned they rendered the operation of positioning slowto accomplish. The present object is to provide a stock-gage which maybe adjusted with reference to the pattern, but without contacttherewith, and according to a scale which may be readilyfollowed,whereby the adjustment may be effected very quickly and thespeed of operation thus greatly increased. In carrying out the inventionit is preferred to follow a system which involves providing the patternswith holes, at which they are fastened in the ma chine, positioned inaccordance with a scale corresponding with a scale or scales upon thestock-gage, all as will be fully described later on.

The drawings show the improved stockgage in two forms, the main pointsof difference being that one employs gage-adjusting mechanism operatedby swinging levers and the other gage-adjusting mechanism operated byturning levers or screws.

In the drawings, Figure l is a front elevation of a sole-roundingmachine of the Loewer type with the improved stock-gage of the firstsaidform applied thereto; Fig. 2, an enlarged section taken on line 2 ofFig. 1 and viewed in the direction of the arrow; Fig. 3, an enlargedsection taken. on line 3 of Fig. 1 and viewed in the direction of thearrow; Fig. 4, an enlarged broken section of a patternclamp; Fig. 5, aplan section taken on line 5 of Fig. 3; Fig. 6, a sectional view showinga detail of the construction, the section being taken on line 6 of Fig.7; Fig. 7, a broken section taken on line 7 of Fig. 6; Fig. 8, a brokensection of a rod forming a detail of the construction and marked with .ascale; Fig. 9, a plan view of a sole-pattern; Fig. 10, a View inelevation of the improved stoclc gage of the second said form; Fig. 11,an enlarged broken section taken 011 line 11 of Fig. Fig. 12, a plansection taken on line 12 of Fig. 10; Fig. 13, an enlarged section takenon line 13 of Fig. 12; Figs. 14: and 15, en-

larged and brokensections taken, respectively, on-lines 14 and 15 ofFig. 10; Fig. 16, a plan section taken on line 16 of Fig. 10, and Fig.17 an enlarged broken elevation of one side of the detail shown in Fig.16.

As the improvement in either form is mounted upon the vibrating carriageor swinging frame of the machine only that much of the machine isillustrated in the drawings, for the reason that the construction andoperation of the rotary cutters and other parts are well known in theart.

A is a part of the main frame of the machine, and B the vibratingcarrier or swing- I00 turning of a hand-wheel .90.

ing frame, pivotally mounted at its lower end upon a shaft t. Journaledin the frame B is a shaft comprising sections O, O, and O 011 the outerend of the section O is a drive-wheel s, which may be an elliptoid, asshown in the aforesaid Loewer patent, and upon the inner end of the samesection is the member a" of a pattern-clamp D. The shaft-section 0slides longitudinally in its bearings and is provided at one end withthe member 0" of the clamp D and at its opposite end with the member (1of a stock-clamp E. The shaft-section O is provided at its inner endwith the member q of the clamp D and is adapted to be movedlongitudinally in its bearing by the The members of the clamp D areprovided with smooth flat clamping-faces, and on the member 0" are pins1- 1- which occupy a certain predetermined position and enter sockets 0'0- in the memher 1'. On the shaft-section C is a suitable spring 19,which tends to press the member 7' against the member 0.

Referring first to the construction of the stock-gage shown in Figs. 1to 8, inclusive, on the frame B, in the position shown, is a boss orbracket n, from which extends a bar a, which may be square incross-section, as shown. Fitting and sliding upon the bar 41 is a sleevem, forming a part of the supporting-frame of the stockgage F. Fastenedupon the frame B, toward the upper end of the latter, is a segmental baror yoke Z Pivoted at its lower end to a bracket Z on the frame B is alever m, pivotally connected between its ends at m to the sleeve m andat its upper end sliding along the segmental bar I. On the lever m atthe bar Z is a bracket 171 which extends over the bar Z and is providedwith a clamp-screw m, which may be turned to engage the barl and holdthe lever m in adjusted position. \Vhile a clampscrew in is shown forfastening the lever m against movement upon the bar I, any othersuitable fastening means may be employed. On the sleeve on, and formingan integral part thereof, is a sleeve m extending at right angles to thesleeve m and provided through it with an opening an. Integral with thesleeve m is a sectoral plate m provided with a segmental slot m in thearc of a circle of which the sleeve-opening m is the center. Extendingthrough the opening hi is a bar 7;. Fixed to the bar It, above thesleeve m is a collar and also fixed to the bar 70, below the sleeve of,is a sleeve k carrying an arm k Pivotal] y mounted in the outer endportion of the arm is a catch is, and at the peripheral edge of theplate m on the under side thereof, is a flange m provided with notches mon in the positions indicated in Fig. 1. The collar 70 and sleeve 70prevent longitudinal movement of the bar 70 in the sleeve m but permitit to be rotated between the two positions wherein the catch k engagesthe notches m m. On the upper end of the bar 70 is an arm 7& and at thelower end thereof is an arm 70 which extends parallel with the arm kFastened at its upper and lower ends, respectively, in the arms 70 k isa guide-rod 70 which extends parallel with the bar 7c and passes throughthe segmental opening m in the plate m and through an opening in the arm70 On the lower end portion of the bar 70 is an arm i, having a sleeveportion i, which surrounds and slides upon the bar 75, a sleeve portion75 which surrounds and slides upon the guide-rod 7t, and anupward-extending finger portion Adjustably secured to the finger i is alower gage member or gage-plate i having a downward-extending finger iwhich is attached to the finger by means of a clamp-screw i. Thegage-plate 2' may be raised and lowered with reference to the arm i byloosening the clamp-screw i and may be fastened in adjusted position bytightening the set-screw. At the sleeve 11 is a yoke i provided withopenings to receive the bar 7; on opposite sides of the sleeve and slidewith the said sleeve upon the bar. Sliding upon the bar 7c above thearmiis an arm h, having a sleeve portion 7b, which surrounds the bar 70,a sleeve portion 7L2, which slides upon the guide-rod 70 and anupward-extendin g finger 7L3, bent to a right angle at its upper endportion. Adjustable upon the finger 7b3 is a gage member or middlestock-gage 7L4, mounted upon a finger 7L5, secured to the finger 77, bymeans of a thumb-screw h. The finger 71 may be slid longitudinally uponthe finger [L3 to a limited extent and fastened in adjusted position bymeans of the thumb-screw h. At the sleeve portion 71/ of the arm h is ayoke h having openings through it to receive and slide upon the bar 7sat opposite sides of and with the said sleeve. Above the plate m is anarm g, having a sleeve portion g, which surrounds and slides upon thebar 7o, a sleeve portion 9 which fits around and slides upon theguide-rod 70 and abent finger 9 Mounted upon the finger g is a gagemember or upper stock-gage 9 having an arm or finger g, which isadjustably secured to the finger g by means of a thumb-screw g. Thefinger g may be slid to a limited extent upon the finger and fastenedin. adjustable position by means of the thumb-screw g. At the sleeveportion gis a yoke gZhaving openings through it to receive and slideupon the bar 7; on opposite sides of and with the said sleeve. Fulcrumedat 1 upon the stationary sleeve on is a lever f, connected at its longarm, through the medium of a link f, with the yoke 2' A linkg connectsthe lever f, between the link f and fulcrum y, with the yoke 7L7. Thelink f is in two overlapping parts, which slid e upon each other and areheld together by means of a screw f thus rendering it possible toshorten or elongate the lever, as desired. A link f connects the shortarm of the lever f with the yoke The link f is also constructed. to belengthened and shortened, as desired, it being formed of overlappingsections held together by a screw f In the sole-roundin g machine shownin Fig. 1 of the drawings the member 1' of the pattern-clamp D and themember q of the stockclamp E are in rigid relation and extend in thesame plane. When the machine is started, it rotates the member 'I' ofthe pattern-clamp one complete revolution and then stops, and thedriving mechanism is so arranged that the member 0", its companionmember r, and the stock-clamp will always stop at a certain fixedposition, in which position the pins r are at a slight angle to thevertical plane. The patterns Z employed in the machine are preferably,though not necessarily, of sheet metal and provided with openings 2 a,which, as it is preferred to provide them, are located in the ball andheel portions, as shown in Fig. 9. The openings 2 a register exactlywith the pins 0*, and while the location of the said pins may bechanged, if desired, it is necessary that each pattern used with themachine shall have openings 2 .2 which conform exactly in location withthe pins. The pattern is placed in position in the machine before thestock Y is inserted, and this is accomplished by moving the clamp member9' to the right in Fig. 1 against the resistance of the spring 19 topermit the placing of the pattern upon the pins 0' The clamp is closedby the resilience of the spring 19, whereby the pattern is held firmlybetween the members 1' r. The stock Y, known as block-stock, andpreviously cut to a shape more or less nearly approximating that of thepattern, is placed in position by opening the clamp E, which is done byturning the wheel 00 in one direction, and fastened in place by turningthe wheel 00 in the opposite direction. The pressure exerted by theclamp member q against the stock and through the latter against the Iclamp member q and clamp D holds the parts firmly together,whereby inthe rotation of the drive-wheel 8 they will all turn together. As beforestated, it is necessary that in placing the stock in the clamp E itshall be so positioned with relation to the pattern that the rotarycutters may act more or less upon the entire edge portion of each blankor individual piece of block-stock.

I11 practicing our invention we prefer to follow a certainsystem, whichmaybe brie fly described as follows:

The machine, it will be understood, is capable of operating upon bothinsoles and outsoles of all sizes and shapes. Having established astandard for the position of the pins 7' according to two, or perhapsthree, widelyvarying sizes, which standard will be preferably common toall machines, each pattern Z will be provided with holes 5 .2", whichwill register exactly with the pins. It may be stated that in practicethe upper pin 1- in Fig. 4, which is the pin intended to be engaged bythe openings 5 of all the patterns,

will always be provided at a certain fixed distance from the center ofrotation of the shaftsections 0 C. For patterns of large size, such asthose for mens shoes, a clamp D would be provided, having the lower pin0" as far or farther from the center of rotation of the shaft-sectionsthan the upper pin 1*. For the patterns of small-sized soles, as forchildrens shoes, the lower pin r may be near the center of rotation ofthe shaft-sections O C. In practice not more than two or three difierentclamps D need be provided for a machine, the larger patterns used havingholes 2 z to fit the pins of the larger clamp and the smaller patternshaving holes 2 a to fit the pins of the smaller clamp.

The stock-clamp E should be of a size, especially when working uponinsoles, nearly approximating the size of the pattern, in order that itmay hold the stock as nearly as convenient to the edge portion of thelatter while itis being operated upon by the cutters. In practice oneclamp E will do, especially when the machine is working upon flexibleinsoles, for but a limited number of sizes, both with relation to lengthand width.

It is necessary in positioning the stock in the clamp E provided thatthe stock shall project more or less from all sides of the clamp and bein such position in the clamp that in its movement in accordance withthe pattern the cutters will cut more or less from all sides of thestock and the clamp will never come into contact with the knives. Forthis reason it is desirablein practice to provide the holes z z ofpatterns Z of different sizes atdifferent distances from the inner edge,which is the edge 22 of the pattern, the holes being each at an equaldistance from the farthest projecting portions of the said inner edge atthe ball and heel port-ions of the pattern. In other words, the holes 22 should be equidistant from the dotted straight line shown in Fig. 9.In practicing the said system the holes 2 z of each pattern are punchedat equal distances from the inner edge of the pattern, varying, as maybe desirable, according to the width and shape of the pattern, by stagesof one-sixteenth of an inch, and 011 each pattern the distance ismarked, as shown at the top of the pattern in Fig. 9, where the numeralXIV indicates that the holes .2 z are fourteen-sixteenths of an inchfrom the inner edge. The pattern Z is so placed in the clamp D that theinner edge .2 is toward the operator or front of the machine. On thesegmental bar Z is a scale Z marked with numerals indicating sixteenthsof an inch, and the lever m carries a pointer m which in the movement ofthe lever registers with the scale. Thus according to the numeral markedthereon the lever m may be swung to move the stock-gage frame toward oraway from the vertical plane of the center of rotation of theshaft-sections C G,

and therefore toward and away from the plane of the pins 4*.

In positioning the stock in the clamp E it is located with relation tothree points of the pattern-namely, the point at the lowest part of theheel-seat, the point 2' or farthest projecting inner edge portion of theheel-seat, and the point a or farthest projecting part of the inner edgeof the ball portion. The lower gage member i is intended to position thelower end of the stock with relation to the point 2 of the pattern, themiddle gage member h" to position the stock with relation to the point aof the pattern, and the gage member g to position the stock withrelation to the point a of the pattern, a slight allowance in practicebeing provided for at all three said points to cause the cutters to workupon the material at those parts. The three gage members i 71 g are uponsliding supports, as before described, all of which connect, by means ofthe links described with the lever f, and their link connections aresuch that the member i will be moved a greater distance in the movementof the lever than either the member h or g.

In practice the patterns for soles of different sizes will vary inlength to a much greater degree than they will in the matter of thedistances between the points Z3 2 which mark the points of farthestprotuberance at the end and inner edge of the heel-seat, and the partsof the gage are so connected with the lever that the movement of thegage members will approximate the variations of the three points 2 a Z5in the different sizes and shapes. Pivotally connected at its lower endto the pin i on the yoke t is a rod e, which passes upward looselythrough a plate or bracket e on the sleeve m On the said plate orbracket is a finger e presenting two shoulders e and 6 respectively,affording pointers. Marked upon the rod 6 is a scale c indicating sizes,and the gage members are so mounted with relation to the lever f andscale (2 that when the rod is moved by the action of the lever toregister at, say, the line marked 1 in Fig. 8 with the pointer e thegage members will be in position to conform to the points 2 2 Z5 inaccordance with the pattern of a No. 1 outsole. By raising the leveruntil the figure 1 on the scale 6 registers with the pointer e the gagemembers will be in position to position the stock in conformity to thepoints 5 .2 .2 of the pattern for a No. l insole.

As is well known in the art, two separate sets or series of the samenumbers are generally employed to designate the sizes of lasts, onerelating to childrens shoes and the other to those of adults, and therod 6 and segmental bar Z would be provided, preferably, with two scalesconforming to the two series mentioned.

In operation when soles of a certain size are to be rounded the operatorselects the pattern, noting at the same time the figure at the top,before mentioned. His first operation will be to move the lever m, ifnecessary, to cause the pointer on to register with the proper numeral011 the scale Z corresponding with the said numeral on the pattern. Thelever on may be then secured in adjusted position by turning thethumb-screw m. The operator will then move the lever f until the propernumber in the scale 6 on the rode registers with the pointer on thefinger c If he is to cut insoles, he will select the pointer 6 and if heis to cut outsoles he will select the pointer 6 When the parts are thusadjusted, they maybe fastened against displacement by tightening athumb-screw g in the sleeve portion g which is adapted to engage the rod75'. The adjustment may be effected while the latch is in engagementwith the notch m and the frame consisting of the rod 70, arms h "i g,and gages carried thereby is swung out of the way. After the adjustmentthe said frame is swung to the position wherein the latch engages thenotch m as shown in Fig. 1, which places the gage members in the properlocation to position the stock. The stock is placed in the clamp E andcaused to rest at its heel portion upon the gage member 2 and hear atits inner edge portion against the gage members 7L4 g hen the stock ispositioned, the stock-clamp is first closed and the gagecarrying framethen swung out of the way. The stock is thus in position to be operatedupon by the rotary cutters in the usual manner.

In case that for any reason the block-stock from which soles are to beformed shall have a materially different shape from the pattern-as, forexample, a materially greater concavity or sweep at the shank than thepattern-it may be desirable to position the stock in the stock-clampwith due allowance for such variations. This may also be the case when,as it sometimes happens, the stock is to be cut full or lar er than thepattern. Any such variation from standard requirements may be effectedin this improved stock-gage and still cause the gage members to beproperly positioned by movement of the levers m f with reference to thescales by adjusting the fingers which carry the gage members on theirsupports, as before described, to withdraw one or another of the gagemembers to the desired extent from the position it would occupy understandard requirements.

If desired, the supporting-finger for each gage-carryin g finger may besuitably marked, as at y y in Fig. 2, to indicate the positions that theends of the latter should occupy with reference to the former understandard requirements.

In the construction shown in Figs. 10 to 16, inclusive, (1 is a sleeveadapted to fit and slide upon the preferably-squared bar or shaft or,before mentioned, and which forms the solesupport of the gage-frame. Thesleeve d at its outer end portion is formed into a yoke 01, having athreaded opening (1 in its outer end to receive a threaded rod 0,provided with a handle 0 The inner end of the rod 0 is reduced, as shownat c in Fig. 14, and there IIO enters a socket d in the end of the barn. The reduced portion 0 is provided with a circumferential recess 0which is crossed by a pin 0 extending through the bar 71. Thus the rod 0may rotate in the socket 61 but is held to the bar by the pin 0 Rotationof the rod 0 by means of its handle 0 will move the sleeve cl upon thesaid bar and a gage c is provided upon the bar, as shown in Fig. 12, fora purpose hereinafter described. Integral with or in fixed relation tothe sleeve d and extending at right angles thereto is a sleeve (1,provided through it with a smootly-bored opening Extending through theopening d and confined therein to rotate freely, but withoutlongitudinal play, is a rod or shaft 1), provided alongits lower endportion with sore w-threads Z) of one pitch, between the threads I) andsleeve (Z with a screw-thread b of another pitch, and above the sleeve(Z with a screwthread I) of still another pitch. The thread or threadsI) extend in one direction and the threads b b in the oppositedirection, and in practice it is preferred to provide a screw b with alead of about six threads to the inch, a screw 12 with a lead of aboutnine threads to the inch, and a screw 19 with a lead of abouttwenty-five threads to the inch.

Pivotally mounted upon the upper and lower end portions of the shaft 1)are parallel arms Z2 b respectively, to which is secured at oppositeends a guide-rod 17, extending parallel with the shaft 1). On the upperend of the shaft 1) and fixed thereto is a crank Z2 provided in its freeend portion with a catch in the form of a spring-controlled pin bprovided at its upper end with a handle 12 and tapered at its lower endb to engage a socket h in the upper end of the rod 1), as shown in Fig.11. The arm a, carrying the lower gage member a, has a threaded openingthrough it to travel upon the screw b and is bored in proper location toslide upon the rod 1). The arm aicarrying the middle gage mem ber a hasa threaded opening through it to receive and travel upon the screw b andthe arm a, carrying the upper gage member a has a threaded openingthrough it to receive and travel upon the screw 12 The arms a a areprovided with openings to receive and move upon the rod Marked upon therod 1), preferably at the arm a, is a gage 6 and the arm a may carryinsole and outsole pointers I), as shown in Fig. 10. Fixed upon orformed integral with the sleeve d is a plate (1, having a segmentalupward-extending flange (1*, provided on its upper edge at one endportion witha spring-catch d Integral with the arm 11 is alaterally-projecting finger I), which rides .upon the upper edge of theflange C1 and when moved toward the position shown in Figs. 16 and 17depresses the spring-catch 01 When it reaches the position shown inthose figures, it passes the spring-catch d and bears against a stop d,the end of the spring presenting a shoulder which holds the fingeragainst movement. The spring (i is provided with a projecting lip c1 atwhich it may be engaged by the operator and depressed to permit thefinger I) to he slid across it.

The bearings of the arms a a a at the screw-shaft B are split and may becompressed by means of the screws 3 (shown in Fig. 10) to compensate forwear. The sleeve (1- may also be split, as indicated in Fig. 12, andcompressed by means of screws y to fit snugly upon the bar n. Thesesplit bearings being a common expedient in mechanics, it is not thoughtnecessary to illustrate them more fully or describe them more minutely.The lower gage member a is provided on its under side with aninternally-threaded sleevepiece a, at which it is screwed upon the arma, whereby it may be raised and lowered to adjust it with relation tothe latter. WVhen adjusted, it may be secured by means of a jam-nut aThe plate forming the lower gage a is preferably squared, so that it maybe adjusted by quarter-revolutions upon the arm a. The gage members a 621113 provided at their edges with threaded supporting pins or bolts awhich pass through openings in the arms a a. On each pin or bolt a onthe inner side of the respective arm, is a jam-nut a and on the outerside of the arm is a thumb-nut a By loosening the nuts the gage membersmay be adjusted .toward or away from their supporting-arms and fastenedin adjusted position by means of the nuts a, a

In operation the frame, consisting of the sleeve d and parts carriedthereby, may be positioned in accordance with the numeral on the patternZ, as before described, by turning the crank o with relation to the gagec, the crank c and threaded rod 0 being the equivalent in this respectof the lever m and segmental bar Z of the other construction. Toposition the gage members in accordance with the pattern, the handle 19may be grasped and raised to withdraw the pin b from the socket b andthe crank b turned to rotate the screw-shaft b in accordance with thegage 19 which corresponds with the gage e in the other construction. Theturning of the screwshaft 2) in one direction causes the lower andmiddle gage members to be lowered the predetermined relative distancesand the upper gage member to be raised a predetermined relativedistance. The bearing-sleeve d and the screw-shaft b are in practice atan angle to the vertical plane the same as the bearing-sleeve m andattendant parts in the other construction, whereby the tendency of theframe, consisting of the screw-shaft, arms 1)" b rod b, gage members,and their supporting-arms, is to swing away from the stockengagingposition. In moving the frame to the stock engaging position the fingerZ) slides upon the segmental flange b until it passes and is engaged bythe spring (1 whereby the parts are locked in the stock-engagingposition. Before the machine can be started to turn the stock againstthe rotary cutters the said frame must be swung out of the way of therotating stock, and this may be accom plished by simply depressing thespring (i to release the finger Z), when the frame will swing by gravityout of the path of the stock. In the Loewer sole-rounding machineautomatically-operating means are provided for moving the stock-gage outof the path of the stock when the machine is started, and, if desired,mechanism for the same purpose may be provided for releasing thestock-gage in the present constructions whereby it will move out of theway.

The main object which it is desired to accomplish in both theconstructions shown and described is to afford means whereby the gagemembers may be quickly, readily, and accurately positioned withoutcontacting with the pattern, to the end of effecting materially greatereconomy in the matter of the time required for the positioning operationand greater certainty under all conditions than has been possible in theuse of stock-gages hitherto provided. The difference between the twoconstructions is purely mechanical, and, broadly considered, theiroperations are substantially the same. In minor particulars eachconstruction may be said to have advantages in certain respects over theother. For example, in the construction first described the levers f mmay be moved approximately as quickly to effect a change of severalnumbers as a change of one number in the sizes of soles to besuccessively rounded, while in the construction last described onecomplete rotation of the screw-shaft b will effect a change of but onenumber, and the same may be said of the screw 0. On the other hand, theconstruction last described possesses advantages over the constructionfirst described, because when cutting soles commencing with, say, thelargest size and then adjustin the machine by gradations for smallersizes in regular rotation a single complete turn of the operating-crankwill change the adjustment one size, and the operator need not refer tothe scale each time the pattern is changed.

In practice, to change the gage members from one size pattern to anotherinvolves usually the movement of the lower gage memberone-sixth of aninch, the upper gage mem her one twenty-fifth of an inch, and the middlegage member only one-ninth of an inch in the direction of movement ofthe lower gage member. Thus while a material change is effected in therelative positions of the upper and lower gage members the middle gagemember moves but slightly with relation to the lower gage member. Themovement of the upper gage member being but about one twenty-fifth of aninch with each operation in the construction shown, it is not necessaryin practice that it should be moved with each adjustment of the lowergage members, but

only occasionally, as once for every two or more changes in the sizes ofthe patterns. For this reason, and because it is difficult to providedurable threads as fine as required at the screw b the upper gage membermay have separate independent adjusting means instead of the fine screwb which adjusting means may in practice be operated to move the uppergage member only occasionally, as required. It is within the scope ofthis invention, therefore, to have three or more gage members, of whichonly two or more shall be independently and simultaneously movable tounequal distances.

Vhile the mechanisms shown and described carry out the invention in amanner that is eminently satisfactory, the constructions are susceptibleof modifications in the matter of details without departing from thespirit of the invention as defined by the claims.
